If you trust that office printer to survive a roll down a steep mountain sure.

Your idea of how electromechanical devices "just work" is based on office environments (and even there they fail with astounding regularity today, half a century later).

As an electrical engineer that has repaired many (also very old) devices I don't think you have a realistic idea of why the thing looks as it does. One point is environmental factors (strong vibration, harsh radiation, potential temperature differences etc) another one is risk managment. If your commercial printer fails, how will it fail? You better know exactly what it's failure modes are, because you are the guy who selected that printer and you are reaponsible for both the failure of the mission and the potential death of astronauts who trust you. Still feel secure about the choice? Then you are probably the wrong person for the job.q

TL;DR: look for a certain (recent) submarine failure to see how well your approach works in practise
